Outage Probability of Amplify-and-Forward Cooperation With Full Duplex Relay

Free registration required

Executive Summary

The authors study the outage performance of an Amplify-and-Forward (AF) cooperation with Full Duplex Relaying (FDR). When there exists a non-negligible direct link or Residual Self Interference (RSI), full duplex relaying turns the effective channel into a frequency selective channel. Assuming Minimum Mean Squared Error Decision Feedback Equalization (MMSE-DFE) at the destination, they derive tight closed-form bounds on the outage probability expression for AF-FDR, and study the effect of the direct link and the RSI in the optimal duplex mode selection. It is shown that under a strong direct link, FDR becomes less beneficial due to the persistent noise amplification.
